1. Read This First
• Congratulations on becoming the owner of an Ei Carbon Monoxide Alarm. This
will help protect you and your household from the dangerous effects of Carbon
Monoxide- the silent killer.
• The Carbon Monoxide Alarm (CO Alarm) is powered up by carefully rotating it onto
the mounting plate which activates the on/off switch. The indicator lights will
immediately flash in sequence to show they are working. (For the Display models, the
LCD screen will display all icons). Then wait 15 seconds after connecting the power
before button testing.
• Install a CO Alarm in every room that contains a fuel burning appliance, particularly
rooms where people spend a lot of time e.g. bedrooms, kitchens and sitting rooms.
• In rooms with an appliance, install (preferably) on the ceiling, (300mm from walls)
and between 1m to 3m horizontally from appliance. In rooms remote from the
appliance install at ‘head height’, where the light indicators can be seen.
• Test the Alarm weekly by pressing the test button, and check that the alarm sounds.
• Replace Alarm when the “REPLACE UNIT BY” date has been reached. Check the label
on the side of the alarm.
• Do not fit Alarm until all building work is completed to avoid contamination.

2. Carbon Monoxide – The Silent Killer
2.1 What is Carbon Monoxide ?
Many people are killed each year, and many more suffer ill health from Carbon
Monoxide (CO) poisoning. CO is an invisible, odourless, tasteless and extremely toxic
gas. It is produced by appliances and vehicles burning fuels, such as coal, oil, natural/
bottled gas, paraffin, wood, petrol, diesel, charcoal etc. CO is absorbed by red blood
cells in the lungs in preference to oxygen - this results in rapid damage to the heart
and brain from oxygen starvation.
High levels of CO in a house can be caused by:
• Incorrectly or poorly installed fuel-burning appliances.
• Blocked or cracked chimneys/flues.
• Blocked vents or draught-proofing which makes areas with fuel burning appliances or fireplaces airtight.
• Engines of cars, lawnmowers etc. left running in confined spaces.
• Portable paraffin or gas heaters in badly ventilated rooms.
2.2 What happens when your CO Alarm detects Carbon Monoxide ?
When the Alarm detects potentially dangerous levels of CO, it flashes the red alarm
light immediately and then sounds a loud alarm if the CO persists. Table B below shows
how the CO Alarm reacts to different levels of CO gas and exposure time. At higher
levels of CO the alarm turns on sooner. The rate of flashing of the red light indicates
the level of CO. If your CO Alarm sounds follow the instructions on page 21. NEVER
IGNORE THE ALARM !

Pre-Alarm: When the Alarm detects over 43 ppm CO the red light flashes in accordance
with Table B. This helps locate CO leaks as the unit gives an indication straight away.
(Without this feature the CO level would need to be at 43 ppm CO for typically 72
minutes for an alarm sound to be given). Note the Pre-Alarm signal may be triggered
by CO coming for example, from cooking with gas, from car engines or from nearby
barbecues. This is usually not a concern, unless the Pre-Alarm signal persists until the
alarm sounds and the CO source is unknown.
The display models will display CO concentrations greater than 10ppm in accordance
with Table B.
NOTE: The CO Alarm may sound if cigarette smoke is blown into it, or aerosols are
released nearby.
CO ALARM MEMORY
The CO Alarm memory is an important feature of the CO Alarm where even if the house
is unoccupied during an alarm condition it warns the homeowner that the unit has
previously detected CO gas and been in alarm. The memory feature has two operation
modes:
- memory indication for 24 hour period after alarm.
- memory recall on demand
24 hour memory indicators: After alarm, the RED light will flash at different rates
every minute (approx) depending on the level of CO detected - see Table C.
Memory recall on demand: To review the memory status after initial 24 hours, press
and hold the test button, the red led will flash in accordance to Table C. Display models
will show the peak level of CO measured.

Please note that the memory will also be reset when the unit is switched off.
3. Where to place CO Alarms
3.1 Ideally a Carbon Monoxide Alarm should be installed in:
- Every room containing a fuel burning appliance, and
- Remote rooms where occupants spend a considerable amount of time
- Every bedroom.
However if the number of Carbon Monoxide Alarms to be fitted is limited, the
following points should be considered when deciding where best to fit the alarm(s)
- If there is an appliance in a room where people sleep, place a CO Alarm in this room
- Locate a CO alarm in a room containing a flueless or open-flued appliance, and
- Locate an alarm in a room where the occupant(s) spend most of their time (e.g.
sitting room)
9
- In a bedsit, the CO alarm should be placed as far away from the cooking appliance
as possible, but near to where the person sleeps
- If the appliance is in a room not normally used, such as a boiler room, the CO alarm
should be placed just outside the room so that the alarm will be heard more easily.
3.2 Unsuitable Locations
Do not place the CO Alarm in any of the following areas.
(1) In the immediate vicinity of a cooking appliance (keep it at least 1 metre
horizontally from it).
(2) Outside the building.
(3) In an enclosed space (e.g. in or below a cupboard).
(4) In a damp or humid area.
(5) Directly above a sink or cooker.
(6) Next to a door, window, air vent or anywhere that it would be affected by
draughts.
(7) Next to an extractor fan.
(8) Over heat sources such as radiators or hot air vents.
(9) Where it would be obstructed, e.g. by curtains or furniture.
(10) In an area where the temperature could drop below -10°C or rise above 40°C.
(11) Where dirt or dust could block the sensor.
(12) Where it could be easily knocked or damaged, or where it could be accidentally turned off or removed.
10
(13) In a bathroom or other areas where the CO alarm may be exposed to water splashes, dripping or condensation (e.g. above an electric kettle).
(14) Near paint, thinners, solvent fumes or air fresheners.
3.31 If locating the CO alarm in a room with a fuel burning appliance
(see figure 1)
• If it is mounted on a wall, it should be located at a height greater than the height of
any door or window but still be at least 150mm from the ceiling.
• If it is mounted on the ceiling it should be at least 300mm from any wall or light
fitting.
• The CO alarm should be a horizontal distance of between 1m and 3m from the
potential CO source.
• If there is a partition in the room, the CO alarm should be located on the same side
of the partition as the potential source.
• In rooms with sloped ceilings, the CO alarm should be located at the high side of
the room (see fig 2).
3.32 If locating the CO alarm in a bedroom or in rooms remote from a fuel
burning appliance (see figure3)
• Mount the CO alarm relatively close to the breathing zone of the occupants.
Whatever position is chosen make sure it is possible to view the three light indicators,
when in the vicinity of the alarm.
WARNING: Do not use the CO Alarm on an intermittent basis, or as a portable detector
for the leakage of combustion products from fuel burning appliances or chimneys.

4. Installation
Warning: The Installations of this apparatus should not be used for a subsitute
for proper installation, use and maintenance of fuel buring appliances including
appropriate ventilation and exhaust systems.
4.1 Installation Procedure
1. Select a location complying with the advice in
‘Where to place CO Alarms’ section.
2. Remove the mounting plate from the packaging/
Alarm.
3. Place the mounting plate on the ceiling/wall
exactly where you want to mount the Alarm. With
a pencil, mark the location of the two screw holes.
4. Taking care to avoid any electrical wiring in the
ceiling, drill holes using a 5.0mm drill bit through
the centre of the marked locations. Push the plastic
screw anchors provided into the drilled holes. Screw
the mounting plate to the ceiling/wall.
Figure 4
5. Alternatively, if desired, the CO Alarm will also
free stand on a flat surface with the mounting plate
attached.

If necessary it is possible to further secure or tamperproof the Alarm by using a No.2
or No.4 (2 to 3mm diameter - not supplied) self tapping screw 6 to 8mm long to firmly
lock the Alarm and its mounting plate together (see figure 7).
5. Testing / Monitoring & Maintenance
Testing
Frequent testing of the system is a requirement to ensure its continued and safe
operation. To test the alarm press the hold the test button.
The Green LED will flash and the horn will sound to indicate the alarm is operating
correctly.
Guidelines and best practices for testing are as follows
1.
After the system is installed
2.
Once weekly thereafter
3.
After prolonged absence from the dwelling (.e.g. after holiday period)
4.
After repair or servicing of any of the systems elements or household electrical
works.
Silencing (Hush)
When the Alarm sounds, after sensing CO, pressing the test/hush button will
immediately stop the horn (the red light will continue to flash). If CO is still present the
red light and the horn will turn on again after about 4 minutes. The unit can only be
silenced once during a CO incident. At levels > 150ppm CO the unit cannot be silenced.
16
Monitoring
The Ei207 / 208 series CO alarm will self check (monitor) itself and give a status update
every minute (approx) if there are any problems.
The status of the alarm can also be checked on demand by using the test button. The
table below shows the status response to both the self check and on demand testing.

Maintenance
Clean the outside case by occasionally wiping with a clean damp cloth. Do not use any
cleaning agents, bleaches, detergents or polishes, including those in aerosol cans. Avoid
spraying air fresheners, hair spray, paint or other aerosols near the CO Alarm. Do not
place air fresheners near the unit.
17
Use the narrow nozzle of a vacuum cleaner to remove fluff and other contamination
from the cover slots and gas entry holes.
Caution: Do not paint the CO Alarm.
Remove the CO Alarm when decorating. Do not allow water or dust to contaminate
the Alarm.
Warning: Do not open or tamper with the CO Alarm. There are no user serviceable
parts inside and this can damage the Alarm.
Battery Replacement (For Ei207 Models Only)
Check the ‘Replace by’ label on the side wall - if it
has been exceeded replace the entire unit. If the
Replace by’ label on the side wall has not been
exceeded, remove the Alarm from the mounting
plate, remove the battery cover (see figure 8)
and replace the batteries. Use only the following
Alkaline AAA size batteries: Duracell, Panasonic,
or Energizer.
Insert the new batteries with the orientation shown
on the base. Replace the battery cover and replace
the Alarm back on its mounting plate (this action
automatically switches on the batteries). Button
test the Alarm (after 15 seconds) to check the
batteries are installed correctly and that they are
not depleted.
18
Figure 8
(For Ei208 Models Only) These alarms uses powered for life lithium batteries and are
not replaceable. Check the ‘Replace by’ label on the side wall - if it has been exceeded
replace the entire unit. If the ‘Replace by’ date has not been exceeded, then the Alarm
maybe faulty and needs to be returned to the manufacturer – (See ‘Getting the CO
Alarm Serviced’ section.
For environmentally sound disposal, remove the Alarm from its mounting plate
(for Ei207 models, open the battery door and remove the batteries) and dispose in
accordance with best practice and guidance on WEEE disposal and recycling.
Quick Test with Carbon Monoxide
The Carbon Monoxide Alarm checks for CO gas every
4 seconds and when exposed to the CO gas, the red
light will flash (as per Table B) to confirm that it is
detecting the CO gas.
The Alarm can be tested with carbon monoxide gas
by using one of the kits that comes with the gas
either in a glass phial or aerosol can. Follow the
instructions on the kit.
If a test gas kit is not readily available it is also
possible to gas test the Alarm using a joss stick
or cigarette smoke. To do this remove the Alarm
from its base and slide the power switch to the ON
position (See fig 9). Fill a suitable size plastic bag
with smoke from the joss stick or cigarette. Insert
OFF
Position
ON
Position
Figure 9
19
the Alarm into the smoke filled bag and seal it closed. Within seconds, the red light will
begin to flash (as per Table B) to confirm that the Alarm has detected the CO gas in the
bag.
To check the Alarm sound, momentarily press the test button and within seconds the
horn will sound briefly. Slide the power switch to the OFF position and replace the Alarm
on its mounting plate.
6. What to do when the alarm sounds
(1) Open the doors and windows to ventilate the area (see note).
(2) Turn off all fuel appliances where possible and stop using them. (The Alarm can be
silenced immediately by pushing the test/hush button).
(3) Evacuate the property leaving the doors and windows open.
(4) Get medical help immediately for anyone suffering the effects of Carbon Monoxide
poisoning (headache, nausea), and advise that Carbon Monoxide poisoning is
suspected.
(5) Ring your gas or other fuel supplier on their emergency number. Keep the number
in a prominent place.
(6) Do not re-enter the property until the alarm has stopped. (If the alarm has been
silenced by pressing the test/hush button, wait at least 5 minutes so the Alarm can
check that the CO has cleared).
(7) Do not use the fuel appliances again until they have been checked by a registered
installer or equivalent expert.
20
Note: When ventilation is provided by leaving the window and doors open, the CO
build up may have dissipated by the time help arrives and the alarm may have stopped
sounding. Although your problem may appear temporarily solved it is crucial that the
source of the CO is determined and appropriate repairs made.
7. How to Protect your Family
Follow these guidelines to reduce the risk of Carbon Monoxide poisoning.
(1) Know and look out for tell-tale signs that Carbon Monoxide may be present.
These include:- The CO Alarm warning of abnormal levels.
- Staining, sooting or discolouration on or around appliances.
- A pilot light frequently going out.
- A strange smell when an appliance is operating.
- A naked gas flame which is yellow or orange, instead of the normal blue.
- Family members (including pets) exhibiting the “flu-like” symptoms of CO poisoning
described above. If any of these signs are present get the appliance checked out by an
expert before further use. If family members are ill get medical help.
(2) Choose all appliances and vehicles which burn fossil fuels such as coal, oil, natural/
bottled gas, paraffin, wood, petrol, diesel, charcoal etc. with care and have them
professionally installed and regularly maintained.
21
(3) These appliances must “breathe in” air to burn the fuel properly. Know where the
air comes from and ensure vents/air bricks etc. remain unobstructed (particularly after
building work).
(4) The appliances must also “breathe out” the waste gases (including the CO) – usually
through a flue or chimney. Ensure chimneys and flues are not blocked or leaking, and
get them checked every year. Check for excessive rust or cracks on appliances and
pipe work.
(5) Never leave your car, motor bike or lawnmower engine running in the garage with
the garage door closed. Never leave the door from the house to the garage open if
the car is running.
(6) Never adjust your own gas pilot lights.
(7) Never use a gas cooker or a barbecue for home heating.
(8) Children should be warned of the dangers of CO poisoning and instructed never to
touch, or interfere with the CO Alarm. Do not allow small children to press the test/
hush button as they could be subjected to excessive noise when the unit alarms.
(9) Leaving windows or doors slightly open (even a few inches) will significantly reduce
the risk of high levels of CO occurring. The high levels of draught-proofing in modern
houses reduces ventilation and can allow dangerous gases to build up.
(10) Install CO Alarms in all the areas recommended in this booklet.
(11) Recognise that CO poisoning may be the cause when family members suffer from
“flu-like” symptoms when at home but feel better when they are away for extended
periods.

9. Getting the CO Alarm Serviced
If your CO Alarm fails to work after you have carefully read all the instructions,
checked the unit has been installed correctly, and ensured that it has good batteries
connected, return it for repair or replacement. This should be where it was purchased,
or alternatively return it in a padded box to “Customer Assistance and Information” at
the nearest address given on the CO Alarm or in this leaflet. (Remove the Alarm from
the mounting plate before shipping the product). State the nature of the fault, where
the CO Alarm was purchased, and the date of purchase.
10. Guarantee
Ei Electronics guarantees Carbon Monoxide Alarms Models Ei207 (excluding batteries)
for 2 years & models Ei208 for 5 years from date of purchase against any defects that
are due to faulty materials or workmanship. These guarantees only apply to normal
conditions of use and service, and do not include damage resulting from accident,
neglect, misuse, unauthorised dismantling, or contamination howsoever caused. These
guarantees exclude incidental and consequential damage. If the Carbon Monoxide
Alarm should become defective within the guarantee period, it must be returned to
where it was purchased or alternatively to Ei Electronics, carefully packaged, with the
problem clearly stated (see ‘Getting the CO Alarm Serviced’ section) along with proof
of the date of purchase.
We shall at our discretion repair or replace the faulty unit.
24
11. Limitations of CO Alarms
(1) The CO Alarm will not work without good batteries. If the batteries have been
drained the Alarm will not give protection. Button test the Alarm weekly and on return
from holidays and other long absences.
(2) Carbon Monoxide must enter the unit for it to be detected. There may be Carbon
Monoxide in other areas of the house (e.g. downstairs, in a closed room etc) but not in
the vicinity of the CO Alarm. Doors, air draughts and obstructions can prevent the CO
reaching the Alarm. For these reasons we recommend CO Alarms are fitted both near
and in bedrooms, particularly if bedroom doors are closed at night. Additionally install
in rooms where members of the household spend much of their time, and in rooms
with potential sources of CO gas.
(3) The CO Alarm may not be heard. The sound output is loud but it may not be heard
behind a closed door or if it is too far away. RF interconnecting CO Alarms greatly
improves the probability that they will be heard. The Alarm may not wake up somebody
who has taken alcohol or drugs. The alarm sound may be masked by other sounds such
as T.V., stereo, traffic noise etc. Fitting CO Alarms on either side of closed doors will
improve their chance of being heard. This CO Alarm is not designed for people with
impaired hearing.
(4) CO Alarms don’t last indefinitely. CO Alarms are sophisticated electronic devices
with many parts. Although the Alarm and its component parts have undergone
stringent tests, and are designed to be very reliable, it is possible that parts can fail.
Therefore, you should test your CO Alarm weekly. The CO Alarm must be replaced when
the “REPLACE UNIT BY” date has been reached. Check the label on the side of the alarm.
25
(5) CO Alarms are not a substitute for life insurance. House-holders are responsible
for their own insurance. The CO Alarm warns of increasing CO levels, but we do not
guarantee that this will protect everyone from CO poisoning.
(6) CO Alarms are not suitable as early warning Smoke Alarms. Some fires produce
Carbon Monoxide, but the response characteristics of these CO Alarms are such that
they would not give sufficient warning of fire. Smoke Alarms must be fitted to give
early warning of fire.
(7) The CO Alarm does not detect the presence of natural gas (methane), bottled gas
(propane, butane) or other combustible gases. Fit combustion Gas Alarms to detect these.
Note: Carbon Monoxide Alarms, with electrochemical sensors have a cross sensitivity to
hydrogen. This means that they can alarm due to sensing hydrogen being produced by
batteries being incorrectly charged such as on boats or with battery back-up systems
such as those used with alternative energy systems. The unit will alarm with 500 ppm H2
after between 10 and 40 minutes exposure.
WARNING: THIS CO ALARM IS DESIGNED TO PROTECT INDIVIDUALS FROM THE
ACUTE EFFECTS OF CARBON MONOXIDE EXPOSURE. IT WILL NOT FULLY SAFEGUARD
INDIVIDUALS WITH SPECIFIC MEDICAL CONDITIONS. IF IN DOUBT CONSULT A MEDICAL
PRACTITIONER.
26
12. Troubleshooting
ALARM DOES NOT WORK WITH THE TEST BUTTON:
(1) Check the Alarm is secured correctly on the mounting plate.
(2) Wait 15 seconds after connecting the power before button testing.
(3) Hold button down firmly for at least 5 seconds.
(4) Replace batteries (Ei207 models only).
ALARM SOUNDS FOR NO APPARENT REASON:
Follow the detailed instructions in ‘What to do when the alarm sounds’ section.
If there are still problems:
(1) Ensure there are no fuel burning appliances in the vicinity which could be leaking
CO gas (e.g. even from next door).
(2) Ensure there are no fumes in the area (e.g. paint, thinners, hair spray, chemical
cleaners aerosol sprays, damp proofing done with and aqueous emulsion such as
Aminofunctional siloxane and Alkylalkoxysilane.
(3) Ensure there is no outdoor source of CO in the vicinity (e.g. a car with engine
running, heavy traffic, heavy air pollution, barbecue fumes etc).
(4) Ensure there is no source of hydrogen such as batteries being charged (e.g. on boats
or in Uninterruptable Power Supplies (UPS)).
(5) Ensure there is not excessive smoke or fumes from devices such as Egyptian shisha,
hookah or hubbly bubbly pipes, especially those that use coal or charcoal to heat the
tobacco.
27
(6) If the Alarm is fitted with an RF Module, ensure that there are no problems with the
